英文摘要Developing eco-friendly and efficient new antifouling materials is of vital significance to prevent and control the biological fouling of marine equipment in service, as well as water environment safety, marine economy and human health simultaneously. Here, an environment-friendly efficient visible-light antibacterial photocatalyst of P, Mo co-doped TiO2 nanoflower/g-C3N4 material with various defects serving as reactive sites, together with the antibacterial active Mo ion was optimized constructed. First, the one-step hydrothermal method enables the adjustable construction of P, Mo co-doped TiO2 nanoflowers, thereby improving the antibacterial performance and optimizing TiO2-based photocatalytic antibacterial materials. Among them, 0.02 P, Mo-TiO2 (added 0.02 g phosphomolybdic acid) contributes to an enhanced photogenerated active radicals production and has the greatest photocatalytic performance. The co-doping of P, Mo adjusts the band gap structure of TiO2 resulting in a narrowing of the band gap. Then, combining 0.02 P, Mo-TiO2 with two-dimensional porous nanosheet-like g-C3N4 to form 0.02 P, Mo-TiO2/g-C3N4 composite via a simple adsorption deposition method further achieves a more efficient and broad-spectrum responsive photocatalytic antibacterial performance. The 0.02 P, Mo-TiO2/g-C3N4 shows the optimal photocatalytic antibacterial performance, with the sterilization rate of Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa) of 99.08 %, 98.65 % and 99.07 % respectively under visible light illumination of 300 min, which are 2.6 %, 14.4 % and 4.66 % higher than those of the TiO2/g-C3N4. The n-n heterojunctions with the gradient matched band gap structure improve the separation efficiency of photogenerated charge carriers and improves the visible-light photocatalytic performance. Besides, the Mo with an antibacterial performance of metal ion slow-releasing characteristic, similar to silver synergistically functioned during the antibacterial application. Finally, for 0.02 P, Mo-TiO2/g-C3N4, the n-n heterojunction, the increase of adsorption and active sites and the synergistic antibacterial function of Mo together enhanced the visible light photocatalytic antibacterial performance dramatically. Our work provides insights into designing efficient photocatalysts as a promising new antibacterial material for environmental applications.
